This invention relates to ilexiblecable supporters'and its objectsistoprovide a simple inexpensive device for .yieldingly, holding a cable,wireor tube., More specifically its object is'to provide such asupporter which is capable of cushioning the-vibrations of a body towhich thecable or the like is attached.

These and other objectssof my invention will appear-in the followingspecification in which I will describe several devices which embody theinvention, the novel features of which will be set forth in the appendedclaims.

Referring to the drawing?- Figure 1 is a side elevation of a devicewhich is made according to and embodies this invention together with artion of a cable;

Fig. 2 is a, similar view of the parts shown in Fig l, the view beingtaken at right angles to that shown in the latter figure;

Fig. 3 is a side elevation of a modified for of a supporter which alsoembodies the invention together with a portion of a cable;

Fig. 4 is a similar view of the parts shown in Fig. 3, the view beingtaken at right angles to that shown in the latter figure;

Fig.5 is a side elevation of a further modified construction, togetherwith a portion of a cable; Fig. 6 is a similar view of the parts shownin Fig. 5, the view being taken at right angles to that shown in thelatter figure;

Figs. '7 and 8 are side elevations on a larger December 18, 1942, SerialNo. 469,425

scale of a part of the devices shown in the preceding figures,illustrating the way a locking effect is obtained} In Fig. 7 the partsare shown in an initial uncompressed condition and in Fig. 8 the sameparts are shown compressed.

H1 designates a hollow cylinder constructed of a number of coils of wirehelicall wound and in abutting relation. This is a rigid structure andif desired its rigidity may be increased by applying a coat ll of metalas by brazing, soldering or electro-plating. This is shown in Figs. 7and 8. The lower end l2 of this cylinder is normal to the axis of thecylinder.

From the top of the cylinder the wire is wound spirally to form an opencoiled outwardly flaring spring i3 coaxial with the cylinder I 0.

In the construction shown in Figs. 1 and 2 the wire is extended upwardlyas at M, thence in a circular form, as at l5 to the point it where it isbent outwardly and back on itself to form a lip. I! is a portion of thewire parallel to the portion l5 which extends to the point I8 when it isbent outwardly to form another lip. I9 is a straight portion of the wirenormal to the axis of the spring i3 and slightl ofiset from thelip i8.Ata point spaced from-the portion I! the wire is bent slightly to formalip 20 in alinement, in

the view shown in'Fig; 2,'with, the lip l8; Then. the wire is bent ina'circular'form, as at 2|, par-; allel with the portions |5,"il and toform a lip- 22 parallel to the lip I6. When the device is used.

to support a cable with. a'spirally wound sheathingxlip 22 is.disposedtothe left of-the lip 20 instead of directly above it.

The cable C is shown ascircularin' cross sec-. tion having the diameterof that of "the inside diameter of the portions l5, l1 and .21. The distance between the lips 5, I8 and betweenthe lips l8 and 22 is less thanthis diameter but these lips may be sprung apart to admit the cable.

The inside of the cylinder It forms a clearance opening for a screw 30which passes through it into a tapped hole in a body B to which thesupport is affixed. The screw therefore holds the device in an uprightposition.

By reference to Fig. '7 it may be seen that the head of the screw, whichis designated by the reference numeral 3| will clear one or moreconvolutions of the cone shaped spring i3 but will engage ,a part of thespring near the cylinder in. Then when the screw is tightened, as shownin Fig. 8, the lower part of the spring l3 will be flattened and willact like a spring washer as a lock for the screw.

From the foregoing description it is apparent that the cable C isresiliently supported on the body B. Furthermore this resiliency isuniversal in direction. Obviously the spring l3 may become elongated orshortened by relative movements between the cable C and the body B. In

- Fig. 1 the cable is shown at C in dot and dash lines as tilted in onedirection. In Fig. 2 the cable is shown at C and C as deflected into twopossible positions.

The lower part of the modifications shown in Figs. 3, 4, 5 and 6 is thesame as that shown in the precedingfigures. In Figs. 3 and 4 the part ofthe wire above the cone shaped spring I3 is wound into a helix 25 atright angles to the axis of the spring l3 through which the cable C maybe passed.

In Figs. 5 and 6 a clamp is afiixed to the upper end of the conicalspring IS. The lower member of this clamp, designated by 40, has afrustroconical boss 4| projecting from its lower surface which fits intothe spring l3. This lower member-40 is brazed to the spring or afiixedthereto in any other suitable manner. The upper surface of this lowermember is fiat with a semicircular groove 42 running across it. 43 is anupper member the .lower surface of which is flat and has a semi-circulargroove 44 running across it. The cable 0 lies in the groove 42, 44 andthe members 40, 43 are held together by screws 45. 46 designates acentral hole through the members 40 and 43 to give access to the screw39.

Several modifications have been illustrated and described to show thatthe invention is not limitedto any specific form or construction and Iintend no limitations other than those imposed by the following claims.

What I claim is:

1. A flexible supporter comprising a cylinder I of comparatively smalldiameter formed of a plurality of convolutions of wire, and a coneshaped spiral spring formed of the same wire, the axes of the cylinderand of the spring being in the same line, said wire extending from thelarger end of the spring and bent into a form adapted to receive andsupport an elongated member.

2. A flexible supporter comprising a cylinder of comparatively smalldiameter formed of a plurality of convolutions of wire; and a coneshaped spiral spring formed of. the same wire, the axes of the cylinderand of the. spring being in the same line, said. wire extending from thelarger end of the: spring and bent to form parallel spaced arcuateportions of a. diameter corresponding to the transverse dimension of anelongated member to be supported, the ends of said arcuate portionsbeing spaced apart a distance less than said transverse dimension of thesupported member.

3. A flexible supporter comprising a cylinder of comparatively smalldiameter formed of a. plurality of convolutions of wire, and a coneshaped spiral spring formed of the same wire, the axes of the cylinderand of the spring being in the same line, said wire extending from thelarger end of the spring and bent into a helix with its axis normal tothe axis of the cylinder and spring. 1

4. A flexible supporter comprising a cylinder of comparatively smalldiameter formed of a plurality of convolutions of wire, a cone shaped'spiral'spring formed of the same wire, the axes of the cylinder and thespring being in the same line, combined with a headed screw for aflixingsaid supporter to a body, said screw fitting the inside of thecylinderwith its head engaging the smaller convolutions of the coneshaped spring, and member attaching means on the larger end of thespring.

5. A flexible supporter comprising a cylinder of comparatively smalldiameter formed of a plurality of convolutionsof wire, a cone shapedspiral spring formed of the same Wire, the axes of the cylinder and thespring being in the same line, combined with a headed screw for aflixlngsaid supporter to a body, said screw fitting the inside of thecylinder'wi'th its head engaging the smaller convolutions of theconeshaped spring, and a clamp permanently affixed to the larger end ofthe spring.
